Most people give maps to their friends on their birthday. Unfortunately, I am a notoriously bad mapper. This is a very bad map. So instead, in honor of our lovely artist, I give a short little gameplay mod that changes things from Doom to danmaku. Doommaku, if you will.
Danmaku is a phrase that literally means "bullet curtain", and refers to a massive spray of bullets in shmups that coat the screen and must be meticulously and carefully dodged through. People may recognize the more familiar phrase "bullet hell", which has been used to describe Mushihime-sama, eXceed Collection, and Touhou. (Undertale is not bullet hell. Please stop calling it bullet hell)
Gameplay here is very simple. Shoot the oni to win. Dodge bullets to not die. The player's hitbox is dramatically decreased for the sake of easier dodging, and the Crouch button also dodges a la DemonSteele. Hitting alt-fire also obliterates the area in a massive bomb, while giving you temporary invulnerability.
That being said, however, it is feasible to go through the entire battle without once using dodging or bombs. I don't use bombs in this run, and I only dodge to show off in the first phase, so this is to demonstrate that it's actually possible.
